Intercalated discs are the communication junctions between the cells of
- ✓cardiac muscles
- Bstriped muscles
- Cadipose tissue
- Dnerve and striated muscles
✓
Answer
Correct option: A.
cardiac muscles
a
Cardiac muscles are involuntary, cross striated & non-fatigued fibres. Cell junctions fuse the plasma membranes of cardiac muscle cells and make them stick together. Communication junctions (intercalated discs) at some fusion points allow the cells to contract as a unit, i.e., when one cell receives a signal to contract, its neighbouring cells are also stimulated to contract.
